About These Birds
Red-billed Partridge
A small partridge (~225 g) of family Phasianidae, distinguished by its bright red bill on dark plumage. Endemic to montane forests of Sumatra at 700–2,000 m elevation. Inhabits the forest floor and dense undergrowth of subtropical highland forest. Forages for seeds, berries, and invertebrates. Least Concern; restricted to Sumatran mountains but currently stable with sufficient forest cover remaining.
Hill Partridge
Una perdiz de colina robusta (unos 280 g) propia de los bosques del Himalaya y del sur de China. Tiene un collar negro llamativo y partes superiores con vetas y barras complejas. Vive en laderas boscosas entre 1.000 y 3.000 metros de altitud, donde busca su alimento entre la hojarasca. Como muchas perdices, prefiere correr a volar cuando se alarma.
